1. Surface Esterification of Sisal Fibres for use as Reinforcement in Cementitious Matrix
Vegetable fibres have been shown to be promising as reinforcement in composites because they are abundant, renewable, and low cost. However, the fibre-matrix interaction can be damaged by dimensional variation of vegetable fibres, due to moisture variations. The alkaline medium of cementitious matrix is aggressive to natural fibres, compromising their durabi

2. Characterization of free nitrogen fixing bacteria of the genus Azotobacter in organic vegetable-grown Colombian soils
With the purpose of isolating and characterizing free nitrogen fixing bacteria (FNFB) of the genus Azotobacter, soil samples were collected randomly from different vegetable organic cultures with neutral pH in different zones of Boyacá-Colombia. Isolations were done in selective free nitrogen Ashby-Sucrose agar obtaining a recovery of 40%. Twenty four isola

3. Evaluation of enzymatic potential of filamentous fungi isolated from different sources / AvaliaÃÃo do potencial enzimÃtico de fungos filamentosos isolados de diferentes fontes
Enzymes are protein macromolecules responsible for the acceleration of the chemical reactions that maintain and regulate living organisms. They occur in nature and can be from vegetable, animal and microbial sources. Due to high industrial demand the microbial sources are the most used. The filamentous fungi compose the group of microorganisms with highest n

4. Morfologia floral, citometria de fluxo e citogenética em Lycopersicon esculentum Mill. acesso BGH 160 / Floral morphology, flow cytometry and cytogenetic in Lycopersicon esculentum Mill. access BGH 160
Tomato (Lycopersicon esculentum Mill.) is the second most cultivated vegetable in the world. In Latin America the largest producer is Brazil, with a total area of 58,5 thousand hectares and production of 3,3 thousand tons. Part of the increase in production has been attributed to investments in breeding programs and to innovations generated by biotechnical p

5. Aspectos morfoanatômicos e fisiológicos de folhas de sol e de sombra de Lithraea molleoides (Vell.) Engl. (Anacardiaceae)
Face à heterogeneidade dos estratos arbóreos, plantas de florestas tropicais apresentam mudanças estruturais e fisiológicas significativas em resposta às diferentes condições de luminosidade. Adaptações de folhas de um mesmo indivíduo às diferentes intensidades luminosas, constituem a base da diferenciação entre folhas de sol e folhas de sombra

6. Apical cuttings propagation, morphologic and molecular characterization of jabuticaba trees (Myrciaria spp). / Propagação via estacas apicais, caracterização morfológica e molecular de jabuticabeiras (Myrciaria spp).
Com o objetivo de avaliar a influência de diferentes tipos de substratos, valores de pH e concentrações de AIB (Ácido Indolbutírico) no enraizamento de estacas apicais de jabuticabeiras (Myrciaria jaboticaba (Vell.) O. Berg), e caracterizar morfológica e molecularmente espécies de jabuticabeiras, foram realizados dois experimentos. No primeiro, foram

7. Preparo e caracterização de microcapsulas obtidas por polimerização ionica para alimentação de larvas de peixe / Preparation and characterization of microcapsules obtained by polymerization Ionica feeding of fish larvae
This research aimed at producing microcapsules capable of retaining proteins, with the objective of substituting the live organisms used in larval fish feed. Four different polysaccharides: alginate, carrageenan, gelan gum and pectin were used, all having the capacity to form gels by ionic polymerization both individually and in association, in order to prod

8. Preliminary Characterization of Bacteriophages Infecting the Thermophilic Actinomycete Thermomonospora
Bacteriophages lysing strains of Thermomonospora alba and T. fusca were isolated, following specific enrichment, from vegetable composts. Four Thermomonospora phages were distinguished by plaque morphology and host range. Electron microscopy of phage particles, termperature inactivation profiles, and electrophoretic analyses of major virion proteins and geno
